Conor McGregor and his entourage caused mayhem at the end of the UFC 223 media day in Brooklyn by trying to attack some of the fighters on the April 7 card and throwing objects.

According to Ariel Helwani of MMAFighting.com, McGregor and his group threw chairs and a dolly at the bus carrying the fighters and reportedly injured fighter Michael Chiesa in the ambush.

A passenger in the bus was also injured, although it's unclear who that person is.

The bus reportedly was trying to drive the fighters back to the hotel, although many of the fighters were still inside the Barclays Center. McGregor was apparently trying to find rival Khabib Nurmagomedov, who fights Max Holloway in the card’s main event for the lightweight title.

"Do you want to be in business with Conor McGregor right now? Do you want to chase this guy around for interviews and buy his fights? Do you? I don't think anybody is going to want to right now," White said, adding, "I don't know if he's on drugs or what his deal is."

White reportedly returned to the Barclays Center and said McGregor was thrown in jail for his actions, but other reports have emerged that he has not been taken into custody and a warrant is out for his arrest. It has also been reported that his plane can't leave New York.

When contacted by Omnisport, Deputy Commissioner Public Information Stephen P. Davis issued the following statement:

There is no arrest warrant. He is wanted for questioning regarding an incident that took place earlier today at the Barclays Center.

He threw a hand truck at a bus causing an injury to an individual on the bus.

The incident took place at 1:35 pm.

One reason behind McGregor's rampage is White's decision to strip him of the lightweight title — since McGregor has been away from the MMA since 2016, White decided the fight between Nurmagomedov and Holloway would determine the new lightweight champion.

McGregor didn't like that decision and voiced his displeasure on Twitter early Thursday morning.
